about

TLS is the standard protocol
used for securing TCP based Internet traffic. Previous versions of
TLS were known as SSL.
Datagram TLS (DTLS) is a protocol based on TLS that is capable of
securing datagram transport (UDP for instance).

DTLS is well suited for securing applications that are delay
sensitive (and hence use datagram transport), tunnelling
applications (VPN), and applications that tend to run out
of file descriptors or socket buffers.

DTLS is now part of of the OpenSSL repository.
openssl-0.9.8 will probably be the first release with DTLS support.
